Description

The Cooperator will examine how aluminum toxicity, calcium availability, and nitrogen saturation vary with modeled deposition, topography, and edaphic characteristics and how these factors influence the distribution of plant species. This supplemental implementation plan for year 3 describes how we will use lysimeters to correlate soil chemistry data, collected in year 1 and 2 of the project, to soil solution chemistry. This will allow the results of this project to be more useful in assessing the ecological thresholds of critical load models. The project specifically addresses the following objectives: 1. Determine the variability of soil solution chemistry across spruce-fir forests 2.Determine the relationship between bulk soil chemistry and soil solution chemistry 3. Determine if a non-lysimeter method of collecting soil solution samples is applicable to spruce-fir forests of the southern Appalachians
